Autistic alexithymic culture is telling someone that you feel blank or feel nothing, and them getting concerned about you when you don't mean it in the way they thought.
Blank is always taken in a bad context, and I understand logically why since it's often associated with anhedonia and emotional blunting in things like depression, but for me it's literally just my baseline, and pretty much always has been because of how my brain struggles to comprehend emotions. It's not good or bad or even neutral, it literally just feels like nothing: the absence of good, bad, or anything in between.
I'm using the literal definitions of the words, and being autistic, if I felt "bad" or "good" in the most broad senses of the words, I would say that. I may not know the exact name of what I'm feeling, but I have the general idea based on bodily cues or behavioral patterns.
And usually, the general idea for me is absolutely nothing in any direction. Utterly blank.
Why is feeling nothing automatically bad anyway? You'd think it would be the most neutral but nope! Suprise! Now everyone's worried!
